When Jesus died, the curtain to the Holy of Holies was torn in two...all the way. All Jewish scholars, rabbis, leaders knew what that meant. What had previously been available only to High Priests--to approach the living God--was now available to all believers in Jesus Christ our Lord, and my Savior.
Church leaders are to be respected. They are NOT infallible. Catholics basically made that up--along with, say, the fact that Mary was born sinless (!) and never had any other children (!).
(As an aside, I do believe individual Catholics can be saved despite their church's teachings. But not because of them. In spite of them.)
